Abstract excerpt
Trade-offs between life-history components are a central concept of evolution and ecology. Sexual and natural selection seem particularly apt to impose antagonistic selective pressures.

In this study, a genetic trade-off between the sexual and asexual phases of the yeast life cycle was...
